Comparisons. We compare the REN model with other state-of-the-art methods: (1) ResNet-50 [1]}. (2) Domain Adversarial Neural Network(DANN) [2]}. (3) Adversarial Discriminative Domain Adaptation (ADDA) [3]}. (4) Deep transfer learning with joint adaptation networks (JAN) [4]} (5)Conditional Domain Adversarial Network (CDAN) [5]}. (6) Cluster Alignment with a Teacher for Unsupervised Domain Adaptation (CAT) [6]}. (7) Towards Discriminability and Diversity: Batch Nuclear-norm Maximization under Label Insufficient Situations (BNM) [7]}.
